Information processing apparatus and control method thereof

A control method of an information processing apparatus equipped with a touch panel that is able to detect a plurality of touch input positions concurrently, said control method comprising:

• extracting a combination consisting of a predetermined number of touch input positions from a plurality of touch input positions that concurrently exist on said touch panel;
• determining whether or not a combination that is extracted in said extraction step is an area designation operation of a single user based on a positional relationship of touch input positions comprising the combination;
• and
• deciding a designated area based on touch input positions of the combination in a case in which it is determined that the combination is the area designation operation.

A computer readable storage medium that stores a program that causes a computer to execute a control method for an information processing apparatus equipped with a touch panel that is able to detect a plurality of touch input positions concurrently, wherein said program causes the computer to execute a control method comprising:

• extracting a combination consisting of a predetermined number of touch input positions from a plurality of touch input positions that concurrently exist on said touch panel;
• determining whether or not a combination that is extracted in said extraction step is an area designation operation of a single user based on a positional relationship of touch input positions comprising the combination;
• and
• deciding a designated area based on touch input positions of the combination in a case in which it is determined that the combination is the area designation operation.
